The dock is excavated in a direction perpendicular to the quay, container storage devices are installed on both sides of the dock, and cargo can be handled from both sides of the container ship, so that it takes only half the time as before and the cargo handling efficiency can be improved. In addition, a building formed by partitioning the necessary space for exceptional cargo warehouses such as frozen containers, management buildings, empty container warehouses, etc. is installed adjacent to the dock side of the container storage device, and a gate crane, Since a traverser or the like is run, there is no need to provide these buildings separately, and a large space saving can be achieved as a container terminal.

Since the number of export containers per lot is large and lot management is easy, a low-priced, high-stacking-density container storage device is adopted, and imported containers have many sorting destinations and lot management. Because of the difficulty, a temporary container storage device that can be shipped from any storage shelf was adopted, and placed on one side and the other side of the dock, respectively.
Therefore, when transporting a container from the land to these devices by a chassis or a vehicle, one is specialized in carrying in and the other is specialized in carrying out, and the flow of the container is smooth.

The portal crane is provided with a trolley for lifting and unloading containers, and a crane traverser for specialized lateral movement in the crane. The trolley suspends the container with a wire, causing it to roll, making it impossible to start and stop suddenly, and the lateral movement of the container often becomes a bottleneck in cargo handling, but the crane traverser does not have to worry about rolling. High-speed movement can improve the efficiency of cargo handling work.
